PIPE-WRENCH.

SPECIFICATION forming part of Letters Patent No. 776,411, dated November29, 1904.

Application filed M rch 30, 1904. Serial No. 200,670. (No model.)

To all, whom it may concern.-

Be it known that I, GEORGE W. MILLER, a citizen of the United States,residing at Bushnell, in the county of McDonough and State of Illinois,have invented certain new and useful Improvements in Pipe-Wrenches, ofwhich the following is a specification.

My invention relates to improvements in pipe-wrenches, the object beingthe provision of a pipe-wrench which will instantly bite or impinge uponthe pipe and permit the easy turning thereof, which canbe instantlyadjusted to pipes of various sizes, which cannot possibly slip afterbeing adjusted, and which will possess merit in point of simplicity,durability, and inexpensiveness of production.

With this object in View my invention consists of a pipe-wrenchembodying novel features of construction and combinations of parts,substantially as disclosed herein.

Figure 1 represents a side elevation of my wrench with the parts in theposition they occupy when clamping a pipe or when in use. Fig. 2represents a top plan view of the wrench, and Fig. 3 represents a sideelevation with one of the jaws removed.

In the drawings the letter A designates the handle or grasping portionof the wrench, having its lower end provided on one side with therecessed or bifurcated portion B, formed with engaging portions C andhaving its lower end reduced to form the seats I) on each side for thejaws E, which are mounted on the reduced portion by means of the pin F,and the handle is provided with. the lugs G, which are adapted to engagethe wall of the recessed portion H of said jaws, and the reduced portionJ of the handle is formed with the extension K, to which is pivoted oneend of the link L, to the other end of which is pivoted thegrippingchain M, which is adapted to pass around the pipe and fit in therecessed or bifurcated portion B and have the pins N thereon engage theportions 0 of said bifurcated portion, this serving to secure the chainat any desired point. A

It will be observed that I provide a wrench which can be instantlyadjusted to pipes of any desired size and that the pair of jaws beingfree will engage the pipe and instantly bite or impinge against it andsecure a firm hold thereon to permit easy manipulation of the wrench.'It will also be apparent that my wrench is composed of very few partsand cannot possibly get out of order and will withstand the most severeusage and that it can be produced at such a price as to bring it withinreach of all desiring a practical and useful wrench.

I claim 1. A pipe-wrench consisting of the handle, having the bifurcatedportion on one side and having its end reduced to form the seats for thejaws, the pair of jaws pivoted in said seats, and the chain having oneend connected to the reduced end of the handle and constructed to passaround the pipe and engage in the bifurcated portion, said handle havinglugs formed in the curved portion of said seats and said jaws havingrecesses in which said lugs lit and retain the jaws in proper relation.

2. A pipe-wrench consisting of the handle, the bifurcated or recessedportion on one side, the reduced end forming the jaw-seats and havingthe extension, the link pivoted to said extension, the chain connectedto said link and adapted to have its free portion engage the bifurcatedportion, and the pair of jaws pivoted to said reduced end, said handlehaving lugs formed in the curved portion of said seats and said jawshaving recesses in which said lugs lit and retain the jaws in properrelation.
